Kootek® Arduino GY-521 MPU-6050 Module 3 axial gyroscope accelerometer stance tilt module
Hardware Setup
Pin Connections
| MPU6050 | Arduino UNO or FIO |
|---|---|
| VCC | 3.3V |
| GND | GND |
| SDA | A4 |
| SCL | A5 |
| INT | Pin 2 (interrupt #0) |
NOTE: This is a 3.3V device. If using the Arduino UNO or other 5V platform, be sure to power the MPU6050 breakout from the low voltage (3.3V) line. The SDA and SCL inputs will be fine, you do not need to worry about them.

THIS IS HORRIBLE SOLDERING (AND A BLURRY PHOTO)! YOU CAN DO BETTER!

5.0 out of 5 stars Good unit for the right price., December 13, 2012

This review is from: Kootek® Arduino GY-521 MPU-6050 Module 3 axial gyroscope accelerometer stance tilt module (Misc.)
I am fairly new to Arduino projects, so this was a perfect breakout board to get my feet wet. The major down side to this product is that its difficult to find info on it (as said by other users). After finding some code, the unit seems to work pretty well... I used this board on a quadcopter to help with the inherent stability issues.
Hopefully I'll save some people the time to dig up this information. Here is a link for those doing arduino projects:
[...] --> See first comment on this post
here's the source code for the I2C library I used:
[...] --> See first comment on this post
This library contains two helpful examples; one that allows the raw accelerometer and gyroscope values to be accessed, and the other calculates Euler angles, yaw pitch roll, world accelerations, and quaternions. If you using this with an arduino, make sure that the I2C library and a MPU6050 library are in the Arduino sketch folder, this will allow it to compile correctly.
This was also difficult to find:
The GY-521 breakout board is wired to the Arduino Mega as followed:
Vcc - 3.3V
GND - GND
SCL - SCL (pin 21)
SDA - SDA (pin 20)
ADO - GND
INT - D2
The GY-521 breakout board is wired to the Arduino Uno as followed:
Vcc - 3.3V
GND - GND
SCL - D5
SDA - D4
ADO - GND
INT - D2

Hi. I am trying to read the raw data with a Arduino Duemilanove. Would you please tell me how can I wire the GY-521 to the Arduino board. Thank you.

Probably trying to be helpful... but some bad info.... Cost me a good bit of time!!! as I started here!!
Can you EDIT your post please cheeky?
UNO
SCL - A5 (NOT D5)
SDA - A4 (NOT D4)
These are plainly important!
Vcc - Maybe 3.3 works? board seems designed for 5V in with a regulator onboard for sensor??? Mine works on 5V

The Arduino Leonardo/yun has different I2C pin locations as well.
D2=SDA (not A2!)
D3=SCL (not A3!)
And they are also broken out in the same order in the very last two headers by the rest button and mounting hole. I don't own a Leonardo but I believe the silk screen is labeled. You may also have to change any calls as xxx.receive() to xxx.read() for arduino IDE versions 1.0 and higher I believe.
I love arduino but hate trying to recall all the pin functions, seems they constantly move them around.
For those asking, I2C bus usually only needs 4 wires between the device and arduino - ground, voltage, SCL and SDA. Just find the location of SCL/SDA for your specific board.

Did you ground the AD0 pin?
Was INT Connected to D2?
Did you put a 10KOhm Pull-up for the SCL and SDA?
As I'm still getting connection Failed.

The Revolution Will Be Printed in 3-D
Great hope or so much hype?

Defense Distributed's Cody Wilson

There's nothing wrong with listening to nerdy panelists discuss some hip, new technology. But every time you hear one of these well-groomed featherweights whispering words like "revolution" or "democracy" into the mic, try imagining that person smashing his geek glasses into a shiv then charging with a mob toward the nearest authority figure, screaming ¡Viva la Tecnología!
Because that sounds like a true revolution.
Still, it seems there's no other way to say it – the civilized world really is experiencing a 3-D printmaking revolution. By "civilized world," we're talking, of course, about South by Southwest Interactive, which will feature more than half a dozen planned discussions on the topic, not to mention that Bre Pettis – CEO of the world's premier 3-D printmaker company, MakerBot, and the de facto face of this emerging technology – is delivering SXSW Interactive's opening remarks.
Revolutions and democracy, though, have a habit of getting a bit, er, messy with factional fighting between progressive forces and ideological purists. Take Cody Wilson, the "radical freedom"-loving futurist who toldThe Austin Chronicle that many high-profile 3-D makers are "a bunch of Kool-Aid drinkers."
Wilson's made a big, and very unpopular, splash lately for his attempts at a working 3-D printable gun, along with the creation of a nonprofit crowdsourcing website, Defense Distributed, aka "the Wiki Weapon Project." The current enfant terrible of 3-D printmaking and budding provocateur said the media-savvy 3-D makers – Pettis included – prefer to "just represent the Candy Land vision of this technology."
It's not difficult to sympathize with many of Wilson's sentiments (his beef with Pettis began after Wilson's weapon plans were somewhat arbitrarily removed from Pettis' popular Thingiverse). Some of the Interactive Conference's descriptions and titles related to 3-D printmaking – "How 3-D Printing Changed My Life" will cover "the power this technology has in potentially changing the world" – sound as sugary-sweet as Gumdrop Mountain. And then there's the "revolution" itself, which is not only being televised, it's been Web-ized, marketed, and written about to death.
"[3-D printmaking is] at the peak of the Gartner hype cycle, which is a good and a bad thing," said Alice Taylor, founder of London-based 3-D dollmaker MakieLab. "The good thing is, it's completely deserved ... and the bad news is, now we have a traditional 'crash' as all sorts of folks rush in expecting to be able to print themselves a new kidney, or a house on the moon, and being somewhat disappointed that it's not actually quite there yet."
Despite the hype and lofty promise, Taylor said this technology is a "step change" – like the Internet, circa 1995.
"Everyone can see the potential," she said, "but we're not quite sure yet how it'll shake out."
What is clear is that this revolution can and will be monetized and regulated. Recent announcements from the country's two biggest gold diggers – companies and government – prove just that.
During his State of the Union address, President Obama gave a surprising shout-out to 3-D printmaking as one of the industries of America's future, touting the government's $30 million investment into a 3-D printmaking hub in Ohio. "It's probably one of the largest endorsements of 3-D printing that I'm aware of," said Mike Senese, a senior editor at Wiredmagazine.
When it comes to the advancement of the 3-D printmaking industry, though, Senese said he's most excited about established companies beginning to invest in the technology. Last month, Nokia posted the detail files to its phone case and, in a genius bit of both self-promotion and labor cost-cutting, "challenged" those with 3-D printers to make their own, customized cell shells.
"Nokia is opening up the doors for a lot of other companies to follow behind them," said Senese. "So I'm thrilled to see who's next. ... We're just at the very start, and it's really exciting."
Perhaps unsurprising though, among all the panels covering heady topics like The Future and "revolution" and "democratization" hosted by entrepreneurs with positive press coverage, it's the local college student who'd like to keep things simple, DIY.
"There's lots of technicals about the project that just haven't gotten out there that I'm keen to share," said Wilson. "I'm looking at it as more of a technical presentation."
But if you get a chance, ask him about "using progressive language about information to confuse the prohibitionist impulse about certain objects" and "permissive liberal myth[s]." Or the rhetorical he posed to The Austin Chronicle: "Is this a tool for real change? What does it actually mean in the post-capitalist scarcity area when we all have access to the means of production?"
It's some truly revolutionary talk.
